# Essenza by Stefano Contiero

## The work and its context

Essenza is project 356 on the Art Blocks V2 core contract 0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270, published under the canonical slug essenza-by-stefano-contiero and credited to Stefano Contiero. The indexed project record reports a completed edition of 444 of 444 invocations, runtime js@na, and the official description: *The purpose of life is to live.*  **Essenza** is a labor of love. The essence of Art in my eyes. And Art, sometimes, can haunt you. Can consume you.  When you pour yourself into something, it's hard to let it go.  Born from a sketch made more than 3 years ago, this was intended to be my genesis on Art Blocks. It took me another year and a half, countless refinements, Rinascita, more refinements, and a rewrite from scratch to finally be ready to share this with the rest of the world.  It's personal, and it's intense. A fragment of my story. The end of an era, and hopefully, the beginning of a new one.  No matter how hard it can be. If you truly love something, you need to learn how to set it free. [^S01][^S02]

Those figures are current index observations retrieved on 2026-09-19, not a reconstruction of the original public sale announcement. Atlas position is a catalogue ordinal and is not the on-chain project ID. The live collection page and the Hasura projects_metadata row agree on title, slug, contract, and project ID after a filtered query that used the exact slug. [^S01][^S02]

This essay treats the stored artist program, four independently identified outputs, and a freshly checked AB5D holding (or an explicit collection gap) as primary evidence. Metadata traits are cited only when they were returned for the same V2 contract token IDs that were visually inspected. They do not replace looking at the pictures. [^S04][^S09]

## Conception and development

The official project description is the development account used here. Interview or dossier sentences that name a different slug are not treated as statements about this series. *The purpose of life is to live.*  **Essenza** is a labor of love. The essence of Art in my eyes. And Art, sometimes, can haunt you. Can consume you.  When you pour yourself into something, it's hard to let it go.  Born from a sketch made more than 3 years ago, this was intended to be my genesis on Art Blocks. It took me another year and a half, countless refinements, Rinascita, more refinements, 

The development account used here is the specific source named in the citations, not a paraphrase of an artist-dossier page. Where that account is an official project description written in the artist's voice, that limit is stated rather than upgraded into an unpublished studio diary. Where an interview exists, the sentences that actually name Essenza are the ones relied on. [^S07][^S01]

Secondary pages that only repeat the marketplace listing are not treated as independent conception sources. [^S02][^S07]

## How the work was constructed

The complete artist program for slug essenza-by-stefano-contiero was retrieved from projects_metadata.script filtered by that exact slug. The UTF-8 payload is 9523 bytes with SHA-256 a4f5182a841ce2ad76a506d82f98ee5d030b4a7ce47dfe16e51b800f161d1ca0. Runtime on the project record is js@na. The script was read in full; it was not executed in this research session. [^S03]

The stored generator is 9523 bytes, SHA-256 a4f5182a841ce2ad76a506d82f98ee5d030b4a7ce47dfe16e51b800f161d1ca0, runtime js@na. Detected source markers: draw, keydown, requestAnimationFrame, tokenData, hash. Named functions include no function keyword matches. tokenData.hash is read in source. Output then follows the drawing path those functions implement. Token 0 observation: Inspected media-proxy PNG is 2400x2400px, light and muted or near-neutral (mean RGB 245,222,220). File size 1857247 bytes. Indexed features: Rows 3; Type Trio; Extra No; Border No; Chaotic No; Columns 1; Flowing No; Palette Flamingo

Visual claims come from inspected media-proxy PNGs plus indexed token features.

Seed handling is visible in the retrieved program: tokenData.hash is read in source. Time and interaction behaviour in code is: Source contains a continuing-draw or audio/WebGL constructor. The inspected PNG is one frame. Live timing and soundtrack were not captured this session. A handler found in source is not the same thing as a control that was pressed in a live renderer during this session; tested controls are listed only when an actual key or pointer action was performed. [^S03][^S10]

External dependencies are those declared by script_type_and_version plus any library identifiers inside the file. Public visibility of the stored script does not grant a right to redistribute the raw artist source in this package, so the analysis cites functions and byte length rather than reprinting the program. [^S03][^S06]

## The mint

Indexed chronology for project 356 on 0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270 is as follows. First token minted_at is 2022-08-29T18:57:51+00:00. activated_at is 2022-08-31T23:31:29+00:00. start_datetime is 2022-09-12T17:00:00+00:00. completed_at is 2022-09-12T17:53:57+00:00. Invocations stand at 444 of a maximum 444, with complete=true on the retrieved row. [^S02][^S04]

Calculated intervals from those timestamps: first mint to activation is 2.19 days; activation to start_datetime is 11.73 days; start_datetime to completion is 54.0 minutes; first mint to completion is 13.96 days. These are differences of indexed clock fields, not a claim about when a web storefront button became visible to every collector. A first mint that precedes start_datetime is treated as an early or reserved mint unless a separate allocation record is produced. [^S02][^S04]

Indexed clocks: first 2022-08-29T18:57:51+00:00, activated 2022-08-31T23:31:29+00:00, start 2022-09-12T17:00:00+00:00, completed 2022-09-12T17:53:57+00:00. Early first-mint timestamps are not labelled reserved without a separate allocation record.

Historic per-token ETH prices for the original public sale were not recovered from a primary price table during this session and remain unresolved. Any floor price visible on a marketplace page in 2026 is a current listing observation, not the 2021 ask. [^S01][^S02]

## Copyright and licensing

The project record stores the artwork licence label 'CC BY-NC 4.0'. That string includes an explicit 4.0 version and is treated as Creative Commons version 4.0. Code rights for the artist program are not separately labelled on the same field; they are treated as unknown rather than assumed identical to the artwork deed. [^S02][^S06]

Artwork label copied exactly as 'CC BY-NC 4.0'.

Third-party runtime js@na is a separate rights object from both the artwork outputs and the artist source. p5.js, three.js, and ordinary browser JavaScript each keep their own licence texts. This package does not redistribute those libraries. [^S03][^S06]

Original essay prose in this package is dedicated CC0-1.0 by the research operator. That dedication does not change the artwork, code, or dependency licences.

The AB5D header candidate is token 356000215 (edition 215), currently indexed to 0xdd19308a9731cdecb67e0d80ca6823394208c045, which is one of the three linked addresses returned for username ab5d on 2026-09-19. That ownership match is a present-tense index observation, not proof of continuous custody since mint. Inspected media-proxy PNG is 2400x2400px, light and muted or near-neutral (mean RGB 230,230,231). File size 3601741 bytes. Indexed features: Rows 1; Type Macro; Extra Yes; Border No; Chaotic Yes; Columns 1; Flowing No; Palette Nazionale [^S08][^S04][^S09]

Motion, interaction, and audio: Source contains a continuing-draw or audio/WebGL constructor. The inspected PNG is one frame. Live timing and soundtrack were not captured this session. The static PNGs document halt or preview states. They are not by themselves proof that a live loop is still running, nor proof that a work is silent. No soundtrack was heard from these pages during this session. [^S09][^S10][^S03]

## Significance and limitations

Essenza is project 356 by Stefano Contiero on 0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270. The close readings above are the evidence for what the stored program outputs.

Unresolved research questions that remain after this pass: (1) What was the exact public-sale unit price in ETH at start_datetime, supported by a contemporaneous primary source rather than a later floor? (2) For tokens whose live renderer was not stopwatch-timed, what is the measured wall-clock period of one full cycle or one completed progressive draw? (3) What contemporaneous primary source records the original public unit price in ETH? (4) Incomplete Control aside, do any of the three current AB5D wallets later acquire or dispose of the header token used above after 2026-09-19? [^S02][^S08][^S10]

This package is a draft for human review. Structural validation tests file shape, not the truth of seeing or of licence interpretation.
